Yeast is a single-celled fungus that grows naturally in the soil and on the surface of plants. There are hundreds of types of yeast, and while some of them are harmful to humans, others can be beneficial.
For example, yeast can help ferment or leaven foods such as bread, beer, and wine. It can also be used to add flavour to food or improve its texture, as is often the case in the cheese-making industry.
Yeast is naturally rich in B vitamins and is sometimes fortified with additional vitamins and minerals. Therefore, certain types can be used to improve the nutritional value of food or meals. Finally, it can be used as a tool for pharmaceutical drug research, production, or testing to treat a variety of medical conditions.
Nutritional yeast is a highly nutritious food product with several potential health benefits. It can be used to add additional protein, vitamins, minerals, and antioxidants to the diet.
